Kubernetes on AWS

Overview of this book

Docker containers promise to radicalize the way developers and operations build, deploy, and manage applications running on the cloud. Kubernetes provides the orchestration tools you need to realize that promise in production. Kubernetes on AWS guides you in deploying a production-ready Kubernetes cluster on the AWS platform. You will then discover how to utilize the power of Kubernetes, which is one of the fastest growing platforms for production-based container orchestration, to manage and update your applications. Kubernetes is becoming the go-to choice for production-grade deployments of cloud-native applications. This book covers Kubernetes from first principles. You will start by learning about Kubernetes' powerful abstractions - Pods and Services - that make managing container deployments easy. This will be followed by a guided tour through setting up a production-ready Kubernetes cluster on AWS, while learning the techniques you need to successfully deploy and manage your own applications. By the end of the book, you will have gained plenty of hands-on experience with Kubernetes on Amazon Web Services. You will also have picked up some tips on deploying and managing applications, keeping your cluster and applications secure, and ensuring that your whole system is reliable and resilient to failure.

Discovering requirements

The designing requirements are shown in the following diagram:

Availability, capacity, and performance are key properties that we should consider when preparing for production. When gathering the functional requirements for your cluster, it can help to categorize which requirements imply some consideration of these properties.

It is important to understand that it might not be possible to optimize for all three properties without making some trade-offs. For example, for applications that depend on very high network performance, AWS provides a tool called a cluster placement group. This ensures that the best network performance is available by provisioning the EC2 VMs in such a way that fast network interconnections are available between them (presumably by locating them in close proximity within an AWS data center). By provisioning instances this way...
